VPN Loading Question

[Vinnie Saladino]

Is there a formula I can use to calculate the number VPN Users
that a PIX FIrewall can support before it goes belly-up ? Each VPN
tunnel need processing time on the PIX firewall, what percentage of
PIX CPU does a VPN connection use up when the channel is in use?

Any help will be appreciated.

There is a simple VPN calculator on the CCO website, as well as a spec sheet
for the PIX that documents the number of Simultaneous VPNs that can be
supported with and without accelarator cards
